Systematic Electrical Risk Assessment
In complex electrical networks, a simple inspection isn't enough. E-HAZOP (Electrical Hazard and Operability Study) is a structured, team-based brainstorming technique customized from the process industry to identify deviations from design intent that could create hazards.
B2B Industrial Solutions facilitates rigorous E-HAZOP workshops to uncover hidden vulnerabilities in your power distribution system, preventing blackouts, equipment damage, and safety incidents.
The Methodology
Node Selection
Breaking down the electrical system into manageable logical sections (nodes) like HV Switchgear, Transformers, or UPS systems.
MethodologyGuidewords
Applying standard parameters (Voltage, Current, Frequency) against guidewords (More, Less, None, Reverse) to find deviations.
See ExamplesSafeguard Evaluation
Assessing if existing protection (relays, interlocks) is sufficient to handle the identified deviation consequences.
Risk MatrixRecommendations
Providing actionable engineering solutions to reduce risk to ALARP (As Low As Reasonably Practicable) levels.
Sample ReportE-HAZOP vs. Electrical Safety Audit
While audits check compliance, E-HAZOP checks design robustness.
| Feature | Safety Audit (ESA) | E-HAZOP Study |
|---|---|---|
| Timing | Usually Operational Phase | Design Phase or Major Modification |
| Focus | Physical Condition & Compliance | Design Intent & Operational Deviations |
| Approach | Field Inspection / Checklist | Brainstorming Workshop / Theoretical |
| Outcome | Non-Compliance List | Design Improvements & Interlocks |
